WINDOW-FRAM E.

SPECIFICATION forming part of Letters Patent N o. 478,593, dated July12, 1892. Application filed July 18, 1891. Serial No. 399,938. (Nomodel.)

To all whom, it' may concern:

Be it known that I, VILLIAM TURNER GREGG, a citizen of the UnitedStates, residing at Lakeport, in the count)T of Lake and State ofCalifornia, have invented a new and useful Vindow-Frame, of which thefollowing is a specication.

This invention relates to window-frames; and the object thereof is toproduce a windowframe wherein may be removably inserted sliding blinds,screens, duc., especially provided for this purpose.

To this end the invention consists in the specic details of constructionhereinafter more fully described and claimed.

In the drawings, Figure l is a perspective view of a window-frameembodying my improvement, showing a screen-sash therein, the blind-sashremoved. Fig. 2 is an enlarged central cross-section of the frame,showing screen-sash and blind-sash in position therein. Fig. 3 is adiagrammatic elevation of one of the removable strips and an adjacentpart of one of the removable sash.

Referring to the drawings, F designates the frame proper, wherein arethe usual windowsash XV, which may or may not be counterbalanced byweights, as desired.

Within the frame F inside the window-sash, on one side thereof, islocated a stop-molding S, whose outer edge forms the inner bead, againstwhich the upper sash moves, and this molding is provided with grooves G,formed therein, wherein are removably mounted nar row strips N of anysuitable material, preferably wood, and a part of which project from thesaid molding S.

B is a blind-sash, and M is a sash containing gauze, netting, or similarreticulated mate-` rial, or these sash may contain anything that it isdesirable to insert in the window-frame at dierent times. The narrowstrips N are cutin half at about the centers of theirlengths and on abevel or incline I, and the halves of any of said strips may be insertedin grooves G at that side of the said molding S. The edges of theremovable sash B are provided with grooves G', adapted to receive thesaid strips N to form guides therefor. The opposite side of the frame isprovided with a molding S, having integral beads or strips N to enterthe groove G in the adjacentY edges of the sash B. These strips N extendthroughout the length of the window-frame.

In operation, it being desirable to putin one of the removable sash, thelatter is brought into place, its grooved left edge being engaged overthe narrow strip N of the molding S', its body borne into place, and theupper half of one of these removable narrow strips N is inserted in oneof the grooves G in the molding S, the removable sash being at that timeat the lower part of the window-frame. The removable sash is then pushedupward and the lower half of the narrow strip N putin place in suchmanner that the beveled orinclined ends ofthe two halves of the narrowstrip preferably meet at the vertical center of the right side of thewindow-frame. The removable sash can then be raised or lowered, as maybe desired. In the sectional view it will be seen that I have providedthe frame illustrated` with two sets of vertical grooves G, so that bothof the removable sash can be inserted at the same time, if desired, theinsertion of the second sash being similar to that heretofore set forth.To remove either sash, the operation is reversed.

The cutting of the ends of the narrow strips N on a bevel eliects ahighly-important function-namely, the holding of the halves of the stripin place by the removable sash. Obviously if theV ends were cut offsquarely one of the halves would have no means for retaining itin placewhen the sash was standing over the other half; but if the sash be down,as shown in full lines in Fig. 3, the tip of the lower half will holdthe upper half in place, whereas if the sash be up, as shown in dottedlines,'the lower half will be held by the sash bearing against its tip.Hence in either position there is some means for holding both halves inplace and all need for fastening-screws or other devices is avoided.

IIa-ving thus described my invention, what I claim as new is- Thecombination of a window-frame having the usualsash, a stop-moldingforming the inner bead for the upper sash, secured to the window-frameand having grooves formed therein, a like molding on the opposite sideof the Window-frame, having stationary strips or beads projectingtherefrom, removable' strips adapted to be mounted in the groovedmolding and out on oblique lines into halves and ttin g said grooves,and a series of removable sash, each half the height of said molding andhaving a groove at one side adapted to y receive said movable strip anda groove on V the opposite side to engage the strips or beads
